LOCK-ADJUSTER FOR WINDOWS.

Specification of Letters Patent. Patented Sept. 25, 191?.

Application filed January 30, 1915. Serial No. 5,190.

To all whom it may concern.-

Be it known that I, BAYARD E. TAYLOR, a citizen of the United States, and a resident of the town of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Lock-Adjuster for Windows, and I do hereby declare that the following is a full, clear and exact description of the same, reference being had to the accompanying drawings and to the numerals of reference marked. thereon which form a part of this specification.

A great many types of actuating mechanisms and locking devices have been designed for use with windows wherein the sash is hingedly mounted in the casement, for the purpose of swinging the sash to an open or closed position. However, in such types of devices the mechanisms for the purpose are generally mounted upon the interior of the window and are thus more or less unsightly and at times may prove inconvenient when hangings are draped upon the window.

Consequently it is an object of this invention to construct an operating and locking device for a hinged type of window sash which is mounted on the exterior of the window and yet actuatablefrom within, so that no inconvenient mechanisms exist on the interior of the window, and no unsightly operating parts are visible from within.

It is an object of this invention to construct a device for adaptation to windows for operating the same to open and closed position, and more particularly for locking the same in an adjusted or closed position from the interior by simple actuation of a hand wheel for the purpose.

It is furthermore an important object of this invention to construct a bracing and locking mechanism for attachment to window easements having hinged sashes, which is attached on the exterior of the window and is operatable from within, the device when in locked position rigidly holding the sash in an adjusted or closed position and bracing the same rigidly in such position.

It is finally an object of this invention to construct simple mechanisms operatable from the interior of a window to lock the sash in adjusted or closed position, and

when locked incapable of being adjusted from the exterior.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a horizontal section taken through a window casement and sash illustrating a device embodying the principles of my invention attached thereto and with the operation shown in dotted lines.

Fig. 2 is a fragmentary exterior View of one corner of the casement and sash, illustrating the device attached thereon.

Fig. 3 is a detail section taken on 33 of Fig. 2.

Fig. 4: is a detail section taken on line l4l of Fig. 2.

Fig. 5 is a section taken on line 5-5 of Fig. 2.

Fig. 6 is a section taken on line 66 of Fig. 3.

As shown in the drawings:

The window frame or casement is provided with side frame members 1 and 2, respectively, with outer stops 3, secured one on each of said frame members. Connected by means of a hinge 4:, to said frame memher 1, is a swinging window sash denoted as a whole by the reference numeral 5. Bigidly secured by means of countersunk rivets 6, to the surface of one of the outer stops 3, is a bracket 7, having a horizontal exten sion with an apertured boss 8, on the outer end thereof. A long rod 9, of circular cross section is bent substantially at a right angle, as indicated by the reference numeral 10, at one of its ends, and is extended through the aperture in said boss 8, and a pin or other projection 11, is formed upon or secured to said angled end 10, of the rod, and when inserted through said boss passes through a notch 12, provided therefor. Said pin, after the rod has been rotated in the boss a suflicient amount to bring the pin out of register with the notch, acts positively to retain the rod engaged therein. Said rod 9, extends through a telescoping clamping or locking mechanism which is secured upon the exterior of the lower rail of the sash 5, and is actuatable from the interior thereof. This mechanism comprises an outer casing 13, which is secured on the exterior surface of line the sash and projects into an aperture which extends therethrough, and threaded into said casing from the other side of said sash.

through said aperture is a long tubular member 1%, which 1s flanged at its end to receive screws 15, therethrough;bywhichthe same.

may be rigidly attached to the sash on the inner surface thereof.

Slots or openings 16, are formed in the outer. end of. said-casing 13,permitti1 1g saidrod 9, to extend therethrough, anddisposed.

in the outer end of said casing is a split sphere or ball member consisting-10f twov hemispheres denoted respectively by the ref-- erencenumerals 17 and 18, which may be thrust. towardone another to clamp tightly.

top wall of the casing 13, to engage looselyin said notch. In order to thrust said sphere sections 17 and 18, toward one another to clamp tightly upon the rod 9, a tubular member 21, is threaded into the interior of said member .1 1, and at its outer end is provided with a concave recess to permit the sphere section; 17, to seat therein. Longitudinal movement of said member 21, is gained by rotating the same in said member 14, and for thispurpose a long bolt 22, extends into the interior of said tubular member 21, said bolt having a squared end 23, which fits slidably within said tubular member 21, so that longitudinal movement of said bolt within said tubular member is permitted, but the two. are constrained to rotate together. The end of said bolt 22, extends rotatably through the inner endof said member 14:, and is pinned to a suitable actuating head or handwheel 24, which affords a means of rotating;

saidbolt in either direction.

Theoperation is as follows:

In order to adjust the window sash 5, the operator merely turns the head orhand wheeli24, in a direction to cause the .tubular threaded member 21, to thread into .the. member 14:, away from the sphere sections.

17 and 18, thereby loosening the same-and the rod 9, and permitting the rod 9, to slide. easily therethrough. Said rod 9, may then be ,used as .a lever in swinging the sash into anyadjusted position desired, and ,the-en.-.

larged head 25,,on the end thereof prevents the,rod being pulled out of engagement with the clamping mechanism therefor should, byaccident the sashbe swunginto an. extreme position. As clearly-illustrated: by,;the.,dotted lines in Fig,;;1, the; .StLSlLgiS- adapted toswing inwardly, that .is into the room instead of outwardly away from the easement, and the clamping or locking mechanism therefore is-disposed onthe exterior of the sash, although the same is actuatable from the interior. Practically all operations of! adjusting thesashxand locking the same in adjusted position are performed from the-interior, although of course, when the mechanism is released, the sash may be operated-byaperson on the outside of the sash by actuatingthe, rod 9, as for instance when cleaning the window. The device is equally well adapted to sashesswinging.outwardly,r; as for; instance the bracket 7, may then. be mou-ntedon the exterioraof the. easement in V such "a ,positionasto permit clearance thereof; by the sash when the same is iopened. Duestofthe pin..11, which is rigid on the. angled end lO, of the rod 9, said rod .9, cannotbe sprung out of engagement with said bracketpby a pe1'son;.e11deavoring to seek entrance through the window from theexterior.

This device permits theswindow sashtobe swung through any angle of practically no ninety degrees,-inasmuch as .therespective members attached upon the: sash and casement permit a certain degree of rotation of the slidable rod therein before the inner end of theqsashand the --rod 9, contact each other.

Itisobvious thatthe device may be used interchangeably on a" right or left hand opening window. I am aware thatxvarious details of construction. may be varied 109 through a wide r'angewvithout departing v from the principles of this invention, and I therefore do. not purpose limiting the patent granted otherwise than necessitated by. the prior-art.
